Hi,
i have a Table, that consists of temperature data measured with a specific amount of sensors. Now i want to change the Variable Names of the columns with the sensor data to Sensor 1.......Sensor n. The first 3 columns should not be renamed. I want to create a code that gets the number of the sensors and renames them itself. This code should be usable for different measurement without the need to rewrite the code. Thanks in advance!

Variable names exist in the properties of the table.
tblName.Properties.VariableNames
Use indexing to set just the names you want. For example, consider the folowing code for renaming 5 sensors starting at variable 4.
% Create table of 5 rows, 10 variables
A=array2table(rand(5,10))
% Create variable names for 5 sensors
n=5;
sNames = "Sensor " + (1:n);
% rename variables starting at Var4, and including n continguous variables.
A.Properties.VariableNames(4:4+n-1)=sNames

As of release R2020a there's a function named renamevars for renaming table and timetable variables.
